By Reiji Murai TOKYO (Reuters) – Renesas Electronics Corp plans to sell its majority stake in a maker of iPhone display chips to Synaptics Inc, another smartphone chip supplier, according to sources familiar with the matter. Apple Inc had also been in talks about a possible purchase of the stake in Renesas SP Driver in what was seen as a potential move to shore up its global supply chain, but the sources said those talks failed to make progress and Renesas had narrowed its consideration to Synaptics. A Renesas spokesman said the company was considering various options for the unit, including a sale, although no decisions had been made. Synaptics declined to comment.
